5 Application ID: APPLICATION INFORMATION Operator Name: SHELL WESTERN E&P Reason for this Request: REQUEST INFORMATION Economic Technical Other Additional Information for Other Reason for this Request: Is this a proposed injection or disposal well? Is this a Minimum Separation well? Are there any water wells within 1/4 mile of this proposed well location? Are there any INJECTION or DISPOSAL wells within 1/4 mile of the proposed well location? Have there been any blowouts within one mile of this wellsite? WATER WELLS INJECTION OR DISPOSAL WELLS BLOWOUTS

6 Application ID: APPLICATION INFORMATION Operator Name: SHELL WESTERN E&P REQUEST INFORMATION Has the well drilled and completed? Completion Tracking Number: Remarks for the Application: Lead/filler cement is to be pumped at 300% excess. A second stage (see multi-stage lead/filler) is only included in this request plan as a contingency measure to achieve cement returns to surface, in which case the DV tool would be opened. GAU Areal Extent: GAU INFORMATION Radius Distance: Base of Usable Quality Water (feet. determined by GAU): Separation Points: GAU Recommendation Statements: The interval from the land surface to a depth of 350 feet, and the Rustler, the top of which is estimated to occur from 650 to 700 feet depth and the base of which is estimated to occur from 1000 to 1050 feet depth by reconnaissance-level evaluation, must be protected. This recommendation is applicable to all wells within a radius of 800 feet of this location.
